If pros had to change sponsers...

Just wondering, if some pros had to change their clothing sponsers (for whatever reason) - what would you have them wear? For example, I would love to see:
-Federer in something classic, like ST (The classic stuff, not Djoko's) or Fred Perry
-Nadal in something that would be more like what Nike used to be - bold and inituative, like maybe UA (If they make stuff especially for him)
-Djoko back with Adidas
-Murray with Head (apperel) to match his racquet.
-Davydenko with somebody
-Roddick back with reebok
-Hewitt with Nike.
